The MA911B/2 probe is lab grade, gel-filled pH probe for use with Milwaukee Monitors and Controllers.DESIGN FEATURESTop features include:DOUBLE JUNCTIONThe double junction junction design reduces the risk of clogging.SPHERICAL GLASS TIPThe sperical glass tip provide the largest possible surface area for faster results.RESIN BODYThe resin body is tough to withstand accidental knocks and also protects the glass sensing bulb.EXTENDED CABLEOffers a 2m cable for increased flexibility in measuring.USE AND CAREpH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction.SENSING BULBThe glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.REFERENCE JUNCTIONThe reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function. You can extend the life of your pH electrode in the following ways.STORAGEThe pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged. Storing in pH probe storage solution or pH calibration buffers will help address both these issues. Do not store in tap water and DI water. This will damage the sensitivity of the probe. The best way to store the probe is with the probe's cap filled with storage solution or calibiration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage. CLEANINGResidue from the sample can impact the sensitivity of the sensing bulb and block the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution.CALIBRATIONThe pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO pH meter accurate. Also, calibrate after cleaning or a long period of storage.

The MA917B/1 probe makes pH testing easy and fast.Top features include:DOUBLE JUNCTIONThe double junction design reduces risk of clogging with the reference cell physically separated from the intermediate electrolyte.REFILLABLEThe MA917B/1 refillable with MA9011 3.5M KCl. This solution is sliver free. Sliver can cause silver precipitate to form at the junction resulting in clogging. Clogging causes erratic and slow readings. The ability to refill the electrolyte also extends the life of the electrode.GLASS BODYThe glass body is easily cleaned and resistant to chemicals.ROUND TIPThe round design of the tip provides the largest possible surface area for faster readings and is well suited to testing liquid samples.

DESIGN FEATURESThe MA924B/1 offers the following design features:PLATINUM SENSING RINGThe platinum ring design is the preferred for most ORP applications.GLASS BODYGlass body is ideal use in wine applications as it is easily cleaned and gives fast results.DOUBLE JUNCTION REFERENCEThe double junction means that virtually no silver from the reference cell is mixed with the sample and reduces the risks of clogging.REFILLABLEThe ability to refill the electrolyte solution extends the life of the probe. Use MA9011 3.5M KCl fill solution. With a refillable ORP electrode, best results are achieved if the fill cap is removed to create a higher flow rate. This results in a faster and more stable reading.

To ensure measurements remain reliable and accurate, it is important to regularly check the sensor and replace it with a spare sensor if necessary. The replacement sensor is specifically designed for the HORIBA LAQUAtwin Ca-11C for animal blood. This sensor is engineered to optimize user-friendliness and accuracy. With HORIBA replacement sensors, users can be confident that their devices consistently deliver optimal performance and precise results. Advantages of HORIBA Replacement Sensors: Easy Replacement: Sensors can be quickly replaced, allowing measurements to continue without delay. High Accuracy: Replacement sensors ensure that results are precise and reliable. Comprehensive Measurement Range: Various sensor types are available to measure a wide range of parameters. Durability: Sensors are designed for long service life, even under challenging conditions. Sensor Replacement Instructions: To ensure the longevity and accuracy of your HORIBA LAQUAtwin Pocket Tester, please follow these instructions when replacing a sensor: Removing the Sensor: Turn off the tester. Carefully detach the sensor from the device and lift the sensor tip. Completely separate the sensor from the tester so that the two components are no longer connected. Installing the Sensor: Ensure the tester is turned off. Check that the waterproof gasket is clean and intact. Attach the sensor to the tester by inserting hook “A” on the back of the device into hole “a” on the sensor tip. Make sure the waterproof gasket is not twisted. Important: After replacing the sensor, it is essential to follow the steps in the user manual of the respective tester to make the device ready for accurate measurements. These manuals are available with the products. Calibration and, if necessary, conditioning are usually required. How can I tell if my sensor shows signs of wear? Check the sensor condition as follows: Perform a 2-point calibration to assess the sensor’s condition. If an error occurs during calibration, this indicates that the sensor has deteriorated. In this case, replacing the sensor is recommended. Regular checks and timely replacement of sensors are essential to maintain the high standards and reliability of water quality measurements performed with HORIBA LAQUAtwin Pocket Testers.
